A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.

The development and structure of the chimpanzee mandible. (1/1613)

The sites of growth and remodeling, and the associated changes in cortical bone structure, have been studied in the chimpanzee mandible and compared with those previously reported in the human and macaque mandibles. The location of the principal sites of growth, and the distribution of the areas of deposition and resorption in the ramus, were found to be similar in all three species. In the chimpanzee, unlike Man, the bone being deposited at the condyle, posterior border of the ramus and coronoid process was plexiform in nature, indicating very rapid growth. The pattern of remodeling in the mandibular body, on the other hand, showed marked species differences at the chin and on the submandibular lingual surface, which account for the contrasts seen in the adult morphology of these regions. Although the pattern of distribution of cortical densities differed from that of surface remodeling, the information they give is complementary in analysing bone growth. The densest regions were found to coincide with sites of consistent lamellar deposition, while the least dense regions were those where plexiform bone was formed. Areas where remodeling led to the greatest reorientation of bone tissue within the cortex showed the greatest disparity between the two patterns.  (+info)

Expression of the paired-box genes Pax-1 and Pax-9 in limb skeleton development. (2/1613)

Vertebrate Pax genes encode a family of transcription factors that play important roles in embryonic patterning and morphogenesis. Two closely related Pax genes, Pax-1 and Pax-9, are associated with early axial and limb skeleton development. To investigate the role of these genes in cartilage formation we have examined the expression profiles of Pax-1 and Pax-9 in developing chick limb mesenchyme in vivo and in vitro. Both transcripts are detected by reverse transcription polymerase chain reaction and Northern blotting throughout chick limb development, from the early bud stages (Hamburger-Hamilton 20-23) to fully patterned appendages (stage 30). Whole-mount in situ hybridization reveals complex, nonoverlapping expression domains of these two genes. Pax-1 transcripts first appear at the anterior proximal margin of the limb buds, while Pax-9 is expressed more distally at what will be the junction of the autopod and the zeugopod. In situ hybridization to serial sections of the girdles reveals that in the pectoral region Pax-1 is expressed proximally in condensed mesenchyme surrounding the junction of the developing scapula, humerus, and coracoid. In the pelvis, Pax-1 is expressed between the femur and the developing acetabulum and along the ventral edge of the ischium; this transcript was also found in the distal hindlimb along the posterior edge of the fibula. Pax-9 transcripts were not detected in the pectoral girdle at any stage, and only weakly in the pelvis along the ventral ischial margin. In the distal parts of both wings and legs, however, Pax-9 is strongly expressed between the anterior embryonic cartilages (e.g., distal radius or tibia) and the anterior ectodermal ridge. The expression of both genes was strongest in undifferentiated cells of precartilage condensations or at the margins of differentiated cartilages, and was absent from cartilage itself. In micromass cultures of chondrifying limb bud mesenchyme expression of Pax-1 and Pax-9 is maintained for up to 3 days in vitro, most strongly at the end of the culture period during chondrogenic differentiation. As seen in vivo, transcripts are found in loose mesenchyme cells at the outer margins of developing cartilage nodules, and are absent from differentiated chondrocytes at the nodule center. Taken together, these investigations extend previous studies of Pax-1 and Pax-9 expression in embryonic limb development while validating limb bud mesenchyme culture as an accessible experimental system for the study of Pax gene function and regulation. Our in vivo and in vitro observations are discussed with reference to 1) the relationship between somitic and limb expression of these two Pax genes, 2) what regulates this expression in different regions of the embryo, and 3) the putative cellular functions of Pax-1 and Pax-9 in embryonic skeletogenesis.  (+info)

An endocytic pathway essential for renal uptake and activation of the steroid 25-(OH) vitamin D3. (3/1613)

Steroid hormones may enter cells by diffusion through the plasma membrane. However, we demonstrate here that some steroid hormones are taken up by receptor-mediated endocytosis of steroid-carrier complexes. We show that 25-(OH) vitamin D3 in complex with its plasma carrier, the vitamin D-binding protein, is filtered through the glomerulus and reabsorbed in the proximal tubules by the endocytic receptor megalin. Endocytosis is required to preserve 25-(OH) vitamin D3 and to deliver to the cells the precursor for generation of 1,25-(OH)2 vitamin D3, a regulator of the calcium metabolism. Megalin-/- mice are unable to retrieve the steroid from the glomerular filtrate and develop vitamin D deficiency and bone disease.  (+info)

Pleiotropic skeletal and ocular phenotypes of the mouse mutation congenital hydrocephalus (ch/Mf1) arise from a winged helix/forkhead transcriptionfactor gene. (4/1613)

Congenital hydrocephalus is an etiologically diverse, poorly understood, but relatively common birth defect. Most human cases are sporadic with familial forms showing considerable phenotypic and etiologic heterogeneity. We have studied the autosomal recessive mouse mutation congenital hydrocephalus ( ch ) to identify candidate human hydrocephalus genes and their modifiers. ch mice have a congenital, lethal hydrocephalus in association with multiple developmental defects, notably skeletal defects, in tissues derived from the cephalic neural crest. We utilized positional cloning methods to map ch in the vicinity of D13Mit294 and confirm that the ch phenotype is caused by homozygosity for a nonsense mutation in a gene encoding a winged helix/forkhead transcription factor ( Mf1 ). Based on linked genetic markers, we performed detailed phenotypic characterization of mutant homozygotes and heterozygotes to demonstrate the pleiotropic effects of the mutant gene. Surprisingly, ch heterozygotes have the glaucoma-related distinct phenotype of multiple anterior segment defects resembling Axenfeld-Rieger anomaly. We also localized a second member of this gene family ( Hfh1 ), a candidate for other developmental defects, approximately 470 kb proximal to Mf1.  (+info)

Spatial and temporal variations in the expression and secretion of the various growth factors have been demonstrated in osteoblastic cultures and in various experimental and clinical in vivo models, including fracture healing in humans. Local application of various growth factors influences proliferation, differentiation and protein synthesis in osteoblastic cultures and bone formation in different animal models, including experimental fractures and skeletal defects. The BMPs are the only growth factors known to provoke bone formation heterotopically by making undifferentiated mesenchymal cells differentiate into osteoblasts (osteoinduction). BMPs and other growth factors, soon to become commercially available for clinical use, need a delivery system for their sustained release, as the factors are otherwise rapidly absorbed. Some existing systems inhibit bone formation by inducing chronic inflammation or physically by unresorbed carrier obstructing bone formation. New delivery systems are being investigated.  (+info)

Tumor necrosis factor receptor family member RANK mediates osteoclast differentiation and activation induced by osteoprotegerin ligand. (6/1613)

A receptor that mediates osteoprotegerin ligand (OPGL)-induced osteoclast differentiation and activation has been identified via genomic analysis of a primary osteoclast precursor cell cDNA library and is identical to the tumor necrosis factor receptor (TNFR) family member RANK. The RANK mRNA was highly expressed by isolated bone marrow-derived osteoclast progenitors and by mature osteoclasts in vivo. Recombinant OPGL binds specifically to RANK expressed by transfected cell lines and purified osteoclast progenitors. Transgenic mice expressing a soluble RANK-Fc fusion protein have severe osteopetrosis because of a reduction in osteoclasts, similar to OPG transgenic mice. Recombinant RANK-Fc binds with high affinity to OPGL in vitro and blocks osteoclast differentiation and activation in vitro and in vivo. Furthermore, polyclonal Ab against the RANK extracellular domain promotes osteoclastogenesis in bone marrow cultures suggesting that RANK activation mediates the effects of OPGL on the osteoclast pathway. These data indicate that OPGL-induced osteoclastogenesis is directly mediated through RANK on osteoclast precursor cells.  (+info)

Retardation of bone growth in triamcinolone-treated mice. (7/1613)

Immature mice were treated for up to 8 weeks with daily doses of triamcinolone diacetate. The epiphyseal cartilage plate and its surrounding bone from the humeral head were studied histologically at regular intervals. Concomitantly, roentgenographic measurements were performed on the humeri in toto. By the tenth injection significant morphological changes were noted in the cartilaginous plate, followed by complete cessation of bone growth. Severe triglyceride accumulation appeared in the experimental livers and humeral bone marrow. Osteoporosis also occurred and became severe from the fifth week of triamcinolone administration. Possible explanations for the above findings are discussed.  (+info)

Quantitative histology of the human growth plate. (8/1613)

This paper describes a study in the human femur of the relationship between cell division in growth cartilage and overall bone growth. Growth rates for the distal femur from birth to eighteen years were determined from serial radiographs available from the Harpenden Growth Study; An average of 1-4 cm/year was found for the ages of five to eight years. The development of the growth plate is illustrated in a series of photomicrographs of femur sections. These sections were also used for quantitative histology; The length of the proliferation zone was estimated from cell counts to be twenty-four cells per column. On the basis of this value and the measured growth rate, an approximate mean cycle time of twenty days was found for the proliferating cells of the human growth plate. Since the corresponding cycle time is two days for rodent growth plates, which also have a different structure, it is unwise to extrapolate the findings in this tissue from mouse to man.  (+info)

Protein, consisting of 22 amino acids, happens to be the basic building component for the muscles, skin, nails and hair. Intake of protein is essential for hormone and enzyme formation. Carbohydrate acts as the principal source of energy for the proper functioning of the body and muscles. It modulates fat and protein metabolism. Minerals aid in keeping up the water balance of the body. It also helps in bone development and hormone production. Water assists in maintaining a static temperature of the body ...
Bone is much more than a simple, static organ. While its classical functions of mineral storage, organ protection, and locomotion still hold true, further studies into the skeleton have revealed a dynamic system capable of signaling, communication, remodeling, and responding to various stimuli. Overall skeletal health is critically important to maintaining high quality of life. Unfortunately, the skeleton is susceptible to various ailments such as fracture, cancer, and deterioration. Decreased bone mass and structural deterioration may lead to the silent disease of osteoporosis. With limited treatment options, focus has been shifted to prevention. The best method of osteoporosis prevention is to maximize peak bone mass during development. Nutrition plays an important role in developmental bone health and one nutrient is synonymous with skeletal health: milk. Supplying biologically relevant levels of bone specific nutrients, along with various bioactive compounds, milk should be natures perfect ...

Researchers from the Universities of Birmingham and Oxford, funded by the NC3Rs, have developed a new self-structuring model of bone tissue in vitro that can be used instead of experiments on live animals to study bone formation and maturation (ossification). The model is described in a publication in Advanced Biosystems. Cells at the surface of constructs imaged using scanned electron microscopy. (Iordachescu et al. 2017) The process of ossification is studied to understand normal bone development and repair as well as bone disorders. Current animal models of ossification often involve the use of genetically altered mice that are prone to pathological mineralisation. Depending on the experiment, bone fractures may have to be introduced. Differences in bone metabolism and volumes of bone formation between species can mean that mouse models generally provide a limited approximation of ossification in humans. In addition, differences in protocols and inducing agents (such as osteogenic factors or
The potential effects of introducing bone regeneration strategies into environments of disease and damage are often overlooked, despite the fact that many of the signalling pathways in inflammation have effects on bone development and healing. Embryonic stem cells (ESCs) are increasingly being used to develop models of disease and have potential in osteogenic-cell based therapies. Osteogenic differentiation strategies for ESCs are well established, but the response of these cells to tissue damage and inflammation has not yet been investigated, particularly in comparison to primary osteoblasts. Here, proinflammatory cytokines were used as part of an in vitro model to mimic elements of skeletal disease, such as rheumatoid arthritis and non-union fractures. The response of osteogenically differentiated mouse embryonic stem cells (osteo-mESCs) to the proinflammatory cytokines interleukin 1-β (IL-1β), tumour necrosis factor-α (TNF-α) and interferon-γ (IFN-γ), was compared to that of primary ...
[email protected] Supervsiors: Peter Bisschop, Anita Boelen, Andries Kalsbeek & Eric Fliers. Thyroid hormone is essential for normal bone development and maintenance of bone mass in adulthood. Hypothyroidism during childhood causes growth retardation, delayed bone age and short stature, whereas hyperthyroidism accelerates skeletal development and also results in short stature due to premature closure of the growth plates. In adults, hyperthyroidism increases bone resorption and bone formation leading to high bone turnover osteoporosis and associated increased fracture risk.. Apart from the classic Hypothalamus-Pituitary-Thyroid gland (HPT) axis pathway for the effects of thyroid hormone on bone, in the literature there is also evidence of regulation of bone metabolism via the autonomic nervous system, especially its sympathetic branch. Previous work in our group has shown that triiodothyronine (T3) in the brain can modulate glucose production through a sympathetic pathway. Accordingly, we ...

Leg bone pathologies are a common problem in broiler chickens, and they can lead to decreased welfare and poor production performance. It can be speculated that the ae-tiology of some leg bone pathologies lies, to some extent, in suboptimal early life bone development. One factor that can be speculated to affect bone development, and conse-quently leg health, in broiler chickens is application of light. Light has several properties, such as light intensity, color, duration, and schedule. The present thesis focuses on ligh-ting schedules. Aim was to investigate how lighting schedules applied during incubation and in the early post hatch period (the brooding period) affected leg bone development throughout a broilers life and leg health at slaughter age.. In 4 studies, effects of eggshell temperature (EST) and lighting schedule during incuba-tion and in the brooding period on leg bone development, leg health, and production parameters were explored. The first study found that an EST of 39.4°C ...

Long, short, and irregular bones develop by endochondral ossification, where cartilage is replaced by bone. Flat bones develop by intramembranous ossification, where bone develops within sheets of connective tissue. Compact cortical bone, representing about 80 percent of the mature skeleton, supports the body, and features extra thickness at the midpoint in long bones to prevent the bones from bending. Cancellous bone, whose porous structure with small cavities resembles sponge, predominates in the pelvis and the 33 vertebrae from the neck to the tailbone. Bone growth is more complicated than simple elongation or simple enlargement. Most long bones add width on the outside by a process referred to as subperiosteal apposition (layers added to those already existing), while losing bone on the inside by endosteal resorption (breaking down and reabsorbing material at the center of a mass). At the same time, long bones gain in length by adding to the epiphyseal plate (the surface at the end of the ...
TY - JOUR. T1 - The unfolded protein response in skeletal development and homeostasis. AU - Horiuchi, Keisuke. AU - Tohmonda, Takahide. AU - Morioka, Hideo. PY - 2016/3/22. Y1 - 2016/3/22. N2 - Osteoblasts and chondrocytes produce a large number of extracellular matrix proteins to generate and maintain the skeletal system. To cope with their functions as secretory cells, these cells must acquire a considerable capacity for protein synthesis and also the machinery for the quality-control and transport of newly synthesized secreted proteins. The unfolded protein response (UPR) plays a crucial role during the differentiation of these cells to achieve this goal. Unexpectedly, however, studies in the past several years have revealed that the UPR has more extensive functions in skeletal development than was initially assumed, and the UPR critically orchestrates many facets of skeletal development and homeostasis. This review focuses on recent findings on the functions of the UPR in the differentiation ...

I do hope that issues with bone development were looked into. However... I have a feeling that they were not. We have seen cases of abuse that were not abuse. Weve seen families torn apart and even suicides from these cases. Hopefully the family is able to get those things ruled out. The older comments on this article are from family/friends. The story they tell makes more sense to me than the way the article tells it.
When pregnant (whether youre eating healthy or not) your foetus is drawing whatever nutrients it needs from your body stores. You both share a similar blood environment. So you cant eat whatever you want including health damaging foods and expect a healthy baby. Not only will you suffer from nutrient deficiencies, your baby will have to adjust to a nutritionally substandard rather than a nutrient - rich environment which may have unwanted consequences too like inferior brain and bone development. ...

This study presents unique longitudinal data on skeletal maturation in adolescents from a middle-income country. Moreover, the study provides mean growth curves for RUS bone scores which permit the analysis of sex and ethnic differences in patterns of skeletal maturation. The results show that black boys mature later than white boys whereas black as well as white girls mature at the same age. A longitudinal analysis clarifies how this pattern emerges; skeletal maturation in black girls starts to accelerate later than in white girls, but develops faster, whereas in black boys, skeletal maturation starts to accelerate later and then develops at a similar rate.. The differing patterns of skeletal maturity in the two ethnic groups by sex are intriguing. In all populations, girls are more skeletally mature than boys from birth onwards and reach adult bone maturity, on average, 2 years earlier than boys (1.9 years here).2 Similarly, lower socioeconomic status is generally associated with delayed bone ...
To evaluate the effects of Huang Bai (Phellodendron amurense) on growth and maturation in adolescent female rats. Female Sprague-Dawley rats (28 days old; n = 72) were divided into six daily treatment groups: control (distilled water), Huang Bai (100 and 300 mg/kg), recombinant human GH (rhGH; 20 μg/kg), estradiol (1 μg/kg), and triptorelin (100 μg). Body weight, food intake, and vaginal opening were measured daily from postnatal day (PND) 28 to PND 43. Tetracycline (20 mg/kg) was injected on PND 41. After sacrifice on PND 43, the ovaries and uterus were weighed, and the tibias were fixed in 4% paraformaldehyde. Decalcified and dehydrated tibias were sectioned at a thickness of 40 μm, and sectioned tissues were examined with a fluorescence microscope. Insulin-like growth factor (IGF)-1 and bone morphogenetic protein (BMP)-2 were detected using immunohistochemistry. Relative to controls, body weight was higher in the triptorelin group. Bone growth rate increased in the Huang Bai 100 mg/kg (354.00 ±
The study was aimed to evaluate the effect of Biofield Energy Treated vitamin D|sub|3|/sub| and DMEM medium on bone health parameters such as ALP, collagen, and bone mineralization in human bone osteosarcoma cells (MG-63). The test items (TI), were divided into two parts. One part of each sample received the Consciousness Energy Healing Treatment by Haddon Norman Salt and those samples were labeled as the Biofield Energy Treated (BT) samples, while the other parts of each sample were denoted as the untreated test items (UT). The cell viability by MTT assay data showed that the test samples were found as safe in the tested concentrations. The level of ALP was significantly increased by 73.24% and 85.41% in the UT-DMEM + BT-Test TI and BT-DMEM + BT-TI, respectively at 10 µg/mL compared to the UT-DMEM + UT-TI group. Further, ALP level was significantly elevated by 76.71% in the BT-DMEM + UT-TI group at 0.1 µg/mL compared to the untreated. Collagen was significantly increased by 77%, 113.53%, and 98.00%
We saw a decrease in the level of sclerostin in both of these exercise interventions in men, Hinton said. When sclerostin is expressed at high levels, it has a negative impact on bone formation. In both resistance and jump training, the level of sclerostin in the bone goes down, which triggers bone formation.. The other significant change Hinton observed was an increase in the hormone IGF-1. Unlike sclerostin, IGF-1 triggers bone growth. The decrease of harmful sclerostin levels and the increase in beneficial IGF-1 levels confirmed Hintons prior research that found both resistance training and jump training have beneficial effects on bone growth.. To increase bone mass and prevent osteoporosis, Hinton recommends exercising specifically to target bone health. While exercises such as swimming and cycling are beneficial to overall health, these activities do not strengthen the skeleton. Hinton suggests also doing exercise targeted for bone health, such as resistance training and jump ...
Postnatal bone growth involves a dramatic increase in length and girth. Intriguingly, this period of growth is independent of growth hormone and the underlying mechanism is poorly understood. Recently, an IGF2 mutation was identified in humans with early postnatal growth restriction. Here, we show that IGF2 is essential for longitudinal and appositional murine postnatal bone development, which involves proper timing of chondrocyte maturation and perichondrial cell differentiation and survival. Importantly, the Igf2 null mouse model does not represent a simple delay of growth but instead uncoordinated growth plate development. Furthermore, biochemical and two-photon imaging analyses identified elevated and imbalanced glucose metabolism in the Igf2 null mouse. Attenuation of glycolysis rescued the mutant phenotype of premature cartilage maturation, thereby indicating that IGF2 controls bone growth by regulating glucose metabolism in chondrocytes. This work links glucose metabolism with cartilage ...
Question: My child doesnt drink as much milk as he used to. Do you think hes still getting enough vitamin D?. Answer: This is a really common question for children about a year or two of age and older. Some will go from breastfeeding frequently or drinking up to 32 ounces a day of vitamin-enriched formula to drinking virtually no milk at all-sometimes within days or weeks. While the loss of protein and calcium supply is of concern in these kids, its really the loss of nutritional vitamin D supply that worries me most. There are other ways to get protein and calories-and even calcium-but vitamin D deficiency is epidemic among children and hard to find in other food sources.. Whats so important about vitamin D? In addition to its impact on bone development and growth, this crucial nutrient has important immune- regulating and neurological roles. Children deficient in vitamin D are more likely to suffer from respiratory ailments like asthma and may be at increased risk for certain types of ...
Risk Summary Available data from published observational studies did not demonstrate an association of major malformations or other adverse pregnancy outcomes with pantoprazole. In animal reproduction studies, no evidence of adverse development outcomes was observed with pantoprazole. Reproduction studies have been performed in rats at oral doses up to 450 mg/kg/day (about 88 times the recommended human dose) and rabbits at oral doses up to 40 mg/kg/day (about 16 times the recommended human dose) with administration of pantoprazole during organogenesis in pregnant animals and have revealed no evidence of harm to the fetus due to pantoprazole in this study (see Data). A pre- and postnatal development toxicity study in rats with additional endpoints to evaluate the effect on bone development was performed with pantoprazole sodium. Oral pantoprazole doses of 5, 15, and 30 mg/kg/day (approximately 1, 3, and 6 times the human dose of 40 mg/day) were administered to pregnant females from gestation day ...

However, it remains unknown how this supply is maintained throughout childhood growth. Chondroprogenitors in the resting zone are thought to be gradually consumed as they supply cells for longitudinal growth1,2, but this model has never been proved. Here, using clonal genetic tracing with multicolour reporters and functional perturbations, we demonstrate that longitudinal growth during the fetal and neonatal periods involves depletion of chondroprogenitors, whereas later in ...
Bone development is exquisitely controlled in space and period. versions. As our earlier work shows that gain of function mutations upregulate WNT/-Catenin signaling in fibrous dysplasia Csf2 (FD), our results determine Gs as a crucial regulator of osteoblast differentiation by keeping an equilibrium between two essential signaling pathways: Wnt/-catenin and Hh. HH signaling inhibitors created for tumor therapy could be repurposed to take care of HO and additional diseases due to inactivation. The human being skeleton can be a complex body organ that forms during embryogenesis, expands during years as a child, remodels throughout adult existence, and regenerates pursuing damage. The spatial limitations of its temporal lifestyle are exquisitely controlled.

The growth plate, which is also known by the name of epiphyseal plate, is an area of growing tissues along the end of the long bones in a child. The growth plate determines how the length and shape of the bone will be once the child attains puberty. Normally, the growth plate closes once the child has attained puberty. Thus for females, the normal age at which time the growth plate should close is between 12-14 years and for males it is between 14-16 years.

Researchers have long known that the shape, or geometry, of cells influences what goes on inside a cell. The wrong shape can prevent proteins from being produced, promote cell death (apoptosis), or lead to tumors. In the new study, Kevin E. Healy, of the University of California, Berkeley, and colleagues refine this concept. They show that certain changes in gene and protein expression are related not only to cell shape but, more precisely, to the shape of the cell nucleus. The researchers arrayed rat cells derived from bone tissue on glass slides containing 12,000 binding domains or islands. Each cell adopts the shape of a binding island, a process that also affects the shape of the nucleus. The researchers then manipulated the cells, creating a range of geometric shapes and sizes, and monitored the development of the cells over time. Different nuclear shapes were associated with significant changes in the expression of certain genes related to bone development, according to findings ...

(
  • Its main recommendation was that the egg industry (including retailers) should aim to eliminate bone fractures in live birds altogether, using a combination of genetics, house design and nutrition. (
  • Factors that influence the incidence of fractures are the weakness of bones, the design of housing systems and handling at depopulation. (
  • The incidence of weakened bones and fractures is affected by genetics and strain, nutrition, housing system and methods of depopulation and is exacerbated by the high egg output and persistency of lay of modern hybrid strains. (
  • Finally, FAWC adds that hens are subjected to pain as a result of bone fractures. (
  • There is evidence the prevalence of bone fractures in laying hens is not declining and may actually be rising. (
  • Osteoporosis and bone fractures were recognised as welfare concerns soon after cages were introduced over 50 years ago, but it was some time before it was established that osteoporosis was related to the restriction of movement and lack of exercise. (

  • In other forms, individuals may lead a relatively normal life, but have bones that fracture easily. (
  • In still other cases, affected individuals may have only a slightly increased risk for bone fracture. (
  • The idea that impacting fracture fragments was the key aspect in healing led to the development of the Pugh nail and the Richards screw, in the 1950s and 1960s. (
